You're in luck! Try KINIKI, one of the world's leading makers of men's exotic and designer men's underwear and swimwear

I'm a proud owner of their MICRO line of bikinis which are very low fitting in the back (much better than Jockey style of bikinis which I also have). They have hundreds of other styles and colors to choose from too. You should get their full catalog! It's a lot of fun.
